548G-05ILFT

Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The 548G-05ILFT is an integrated frequency synthesizer designed to control frequency clocks, phase locked loops (PLL), and generate high-resolution frequencies for digital electrical systems.

The 548G-05ILFT is an ideal solution for system designers having limited board space. It takes the place of multiple discrete components by carrying out all frequency synthesizer functions on a single IC. Its single IC operation greatly simplifies the design of clock generators, PLLs and frequency synthesizers. By eliminating bulky connectors and link wires between labels, the 548G-05ILFT reduces cost and improves performance.

Application Field

The 548G-05ILFT frequency synthesizer is designed specifically to meet the demand of current clock and timing applications in the process control, data processing and telecommunications markets. It can be used to drive high-resolution frequency clocks, PLLs and frequency synthesizers in a variety of applications, such as: video controllers, broadcast circuits, frequency counters, multiplexers, modulators, demodulators, encoders, decoders, communications, data processors and memory controllers.

Working Principle

The 548G-05ILFT is a frequency synthesizer that consists of an oscillator, a synthesizer and a reference frequency source. The oscillator is a voltage-controlled oscillator (VCO) that produces an output frequency that is dependent upon the frequency of the reference source. The synthesizer consists of a digital-to-analog converter (DAC), multiplexers (MUX) and an adder. The DAC is used to convert the frequency of the reference source into a voltage, which is then applied to the VCO. The MUX is used to select the voltage that is applied to the VCO, while the adder is used to add or subtract the calculated voltage from the reference voltage. This combination of components allows the frequency of the output signal to be controlled in both magnitude and direction.

Conclusion

The 548G-05ILFT frequency synthesizer is a robust and versatile IC that simplifies the design of clock generators, PLLs and frequency synthesizers. Its compact size and integrated design makes it ideal for applications that require a compact yet powerful frequency synthesizer. The 548G-05ILFT is also suitable for a variety of industrial and consumer applications, making it a versatile and convenient solution for system designers.
